Abstract: A method of operating a piston compressor the compressor having a cylinder as well as a piston arranged therein, a carrier housing with a crosshead mounted in the carrier housing, a spacer which connects the cylinder to the carrier housing, as well as a piston rod extending in a longitudinal direction (L) which connects the crosshead to the piston, wherein the spacer has a plurality of support arms, wherein the support arms are connected to and support the cylinder. The method supplies an inlet fluid (FE) at a temperature in the range between −162° C. and −40° C. to the cylinder via the inlet valve, and expels the fluid located in the cylinder via the outlet valve, wherein the outlet fluid (FA) is heated in the cylinder by compression by a temperature difference in the range between 100° C. and 150° C.

Abstract: An electric and hydraulic machine includes a housing defining a motor chamber and a pump chamber, a motor comprising a rotor and a stator positioned within the motor chamber, and a pump comprising a pumping element positioned within the pump chamber, the pumping element movable by the motor to displace fluid in the pump chamber. The pump chamber includes a low-pressure chamber and a high-pressure chamber, a unit inlet defined by the housing and in communication with the low-pressure chamber, and a unit outlet defined by the housing and in communication with the high-pressure chamber. The pump chamber is positioned radially inward of the motor chamber such that the pump is nested within the motor. A radial cooling channel extends in a radial direction from the low-pressure chamber to the motor chamber such that fluid in the pump chamber communicates with the rotor and the stator to cool the motor.

Abstract: An electric drive compressor system (1) comprising: a reciprocating compressor (2) having temperature and pressure sensors (83, 84) for sensing a pressure and temperature of gas prior to compression by the compressor (1) and for sensing a pressure and temperature of gas after compression by the compressor (1); a motor (3) connected to the compressor (1) for driving the compressor (1); a cooling system (4) for cooling the motor (3); and a controller (5) for controlling the motor (3) in real time based on the temperature and pressure sensor readings of the gas prior to and after compression by the compressor (1). Features and advantages of the systems (1) as exemplified are as follows: lightweight and compact design; refrigerant circuit sealed from electric motor for ease of maintenance and service; air cooled from unique fin and airflow passage design, with fan width pulse width modulation; intelligent control system with pressure and temperature sensors/transducers and software; separate compressor working assembly to ensure piston alignment and compression is not affected by heat distortion; separate outer housing and compressor crankcase to ensure leak free operation.
